Abstract
Abstract A new case for colored pencils is provided, which is formed by a cylindrical main case, a cone-shaped upper cap, and a bottom cap. The bottom cap is screwed to the case and functions to lift and lower the pencils in the case supported upright on the bottom cap so that users can easily pick up a piece of selected colored pencil. The bottom cap is also provided with a coin slit and, therefore, the case may be used as a coin saving box after wasting all the pieces of the pencils contained in the case.
